TRANSCRIPT
TL-406 TL-A4
Terra-Lock™ Earth Percussion Anchors are designed to provide drive efficiency and maximise load capacity across a wide range of applications. The Terra-Lock™ 406 load bearing plate is corrosion resistant plastisol coated Steel Zinc with an open face allowing for vegetation establishment. Terra-Lock™ anchor assemblies are all preassembled with specific anchor heads, wire rope tendon, and bearing plates. Patented Gripple technology allows for re-tensioning and negates the need for time consuming crimping.

SPT Count & Gripple Anchor Performance
General information The Standard penetration test (SPT) is widely used to determine the strenght and deformation properties of the course soil. Approximate correlation of properties of drained granular soil are:
Very Loose SPT 0-4 Loose SPT 4-10 Medium Dense SPT 10-30 Dense SPT 30-50 Very Dense > 50
These figures can then be used to obtain typical shear strength and bulk unit weight for each soil.
This information is then used to predict Gripple Anchor Performance in relation to the conditions described.
The following graphs are derived from idealised theoretical calculations and should be used as a guide only. The variablilty of soil types should always be taken into account and on-site testing should always be carried out in order to obtain more accurate resultts.
